Safety

Chapter 1 - Safety
Please Read the Following Carefully! This portion of
the manual contains information regarding all
Stellar manufactured cranes. Some items
contained within this chapter may not apply to your
specific equipment.
Safety should be the number one thought on every
operator’s mind. Three factors should exist for safe
operation: a qualified operator, well-maintained
equipment, and the proper use of this equipment.
The following information should be read and
understood completely by everyone working with
or near the crane before putting the unit into
operation.
Please take note that Stellar Industries, Inc. is not
liable for accidents incurred by the crane because
of non-fulfillment from the operator’s side of current
rules, laws, and regulations.
GENERAL
It is the responsibility of the owner to instruct the
operator in the safe operation of your equipment
and to provide the operator with properly
maintained equipment.
Trainees or untrained persons shall be under the
direct supervision of qualified persons.
Do not operate equipment under the adverse
influence of alcohol, drugs, or medication.
PERSONAL SAFETY
Keep clear of all moving parts.
Always wear the prescribed personal safety devices.
Always wear approved accident-prevention clothing
such as: protective helmets, anti-slip shoes with steel
toes, protective gloves, anti-noise headphones,
protective glasses, and reflective jackets with
breathing apparatus. Consult your employer
regarding current safety regulations and accidentprevention equipment.
Do not wear rings, wristwatch, jewelry, loose-fitting or
hanging clothing such as ties, torn garments, scarves,
unbuttoned jackets or unzipped overalls, which could
get caught up in the moving parts of the crane.
Keep a first-aid box and a fire extinguisher readily
available on the truck. Regularly check to make sure
the fire extinguisher is fully charged and the first-aid
kit is stocked.

Do not use controls and hoses as handholds. These
parts move and cannot provide stable support.
Never allow anyone to ride the crane hook or load.
MAINTENANCE SAFETY
Never modify or alter any of the equipment, whether
mechanical, electrical, or hydraulic, without explicit
approval from Stellar Industries.
Do not perform any maintenance or repair work on
the crane unless authorized and trained to do so.
Release system pressure before attempting to make
any adjustments or repairs.
Do not attempt service or repair when the PTO is
engaged.
Failure to correctly plumb and wire the crane can
cause a malfunction and damage to the crane
and/or operator.
Decals are considered safety equipment. They must
be maintained, as would other safety devices. Do
not remove any Decals. Replace any Decals that
are missing, damaged, or not legible.
The safety instruction plates, notices, load charts and
any other sticker applied to the crane or service
body must be kept legible and in good condition. If
necessary, replace them.
STABILITY
Know the crane components and their capabilities
and limitations. Overloading the crane may result in
serious injury to self and others, and damage to the
equipment and immediate surroundings.
Never exceed manufacturer’s load ratings. These
ratings are based on the machine’s hydraulic,
mechanical, and structural design rather than
stability.
The supporting surface under the service truck must
be able to support the weight of the machine and its
load. Use outrigger pads if necessary.
Park the vehicle on level ground and extend the
outriggers fully out and then down.
Keep feet and legs clear when lowering outrigger
jacks.
Never operate the crane without making sure the
outriggers are positioned on stable, flat ground.

28000 Owner’s Manual

Set the parking brake and disengage the drive axle
before attempting a lift.
LOAD SAFETY
Operate the crane in compliance with the load
capacity chart at all times. Know the weight of the
load being lifted. Do not rely on the overload device
to determine maximum rated loads.
Never use a sling bar or anything larger than the
hook throat that could prevent the hook latch from
closing. This would negate the safety feature.
Do not apply side loads to the booms.
Do not leave a crane load suspended or
unattended.
Do not walk under suspended loads.
Do not position any load over a person nor should
any person be permitted to place him or herself
under a load.

Crane Controls
1. Be familiar with the sequence and operation of
the crane controls.

Do not use the boom or the winch to drag a load.

2. Each individual crane function should have
control function decals. Replace them
immediately if they are missing or illegible.

Do not use the crane boom to push downward onto
anything.

3. Keep hands, feet and control levers free from
mud, grease and oil.

ELECTROCUTION
Allow extra space for swaying power lines in windy
conditions.

4. Be familiar with the remote control and how it
operates before attempting to lift a load.

Keep a minimum of ten feet between any portion of
the crane and an electrical line. Add an additional
12" for every additional 30,000 Volts or less.
Remember - Death or serious injury can occur when
working near power lines or during electrical storms.
Use a signal person when operating near electrical
sources.
ENVIRONMENT
Do not operate the crane during electrical storms.
In extreme cold, allow adequate time to warm the
truck before engaging the PTO. Do not rev the truck
engine and over speed the hydraulic pumps as
permanent damage to the pumps may occur.
Follow the vehicle owner’s manual regarding
operating the vehicle in such adverse conditions.
In dusty work areas, every effort must be taken to
keep dust and sand out of the moving parts of the
machinery.
In high humidity work areas, keep parts as dry as
possible and well lubricated.

5. Be prepared before beginning operation of the
crane:
• All protective guards must be in place.
• Be aware of the surroundings: low branches,
power lines, unstable ground.
• Be sure all safety devices provided are in
place and in good operating condition.
• Be prepared for all situations. Keep fire
extinguisher and first aid kit near.
• Be sure all regular maintenance has been
performed.
• Visually inspect all aspects of the crane for
physical damage.
• Check for fluid leaks.
• Make sure the outriggers are down and stable.

ATTENTION
Stellar Industries, Inc. is not liable for
accidents incurred by the crane
because of the operator’s non-fulfillment
of current rules, laws and regulations

Operation

Chapter 2 - Operation
This chapter contains information regarding the
operation of Stellar manufactured articulating
cranes. Please study the following pages to ensure
your familiarity with the operation process. This
understanding is vital to the safe and efficient
operation of the crane.
Job-Site Set-Up
thoroughly plan the lift before positioning the vehicle.
consider the following:
1. The vehicle should be positioned in an area free
from overhead obstructions to eliminate the need
for repositioning.
2. Position the vehicle so that it is impossible for any
portion of the equipment to come within the
minimum required safe distance of any power line.
Maintain a clearance of at least 10 feet between
any part of the crane, load line, or load, and any
electrical line or apparatus carrying up to 50,000
volts. One foot additional clearance is required for
every additional 30,000 volts or less. Remember to
allow for winds that cause power lines to sway. It is
recommended that a signal person be used when
the vehicle is set-up near power lines.
3. The vehicle should also be positioned on a firm
and level surface that will provide adequate
support for the outrigger loading. Use extreme
caution when setting up near overhanging banks
or excavations.
4. The parking brake must be set on the vehicle and
the drive axle disengaged before performing a
crane operation.
5. The outriggers must be extended to stabilize the
truck before beginning operation.

Operation

Crane Precautions

Crane Transport

1. Movement of the control levers should be
slow and smooth to meter oil flow for safe
operation. Avoid jerky and sudden
movements.
2. The crane controls should be clearly marked
with decals. If these are missing or
illegible,replace immediately. (See Chapter
5: Decals)
3. Lift load slightly off the ground to check the
safety of the cargo. Do not use stability to
determine the safety. Consult the capacity
charts and strictly adhere to them.
4. Be constantly aware of the boom position
when operating the controls.
5. The boom tip should be centered directly
over the load before making the lift to avoid
swinging.
6. Do not drag loads with the crane.
7. Do not attempt to lift fixed loads.
8. Do not load boom in a sideways direction.
9. Know the weight of the rigging and load to
avoid overloading the crane.
10. Do not extend or rotate a load over
anyone.
11. Wear protective gear such as hard hat,
safety glasses, steel-toed boots, and gloves.

Before transporting the crane, do the following:
1. The crane must be in the stored position.
2. Outriggers must be securely stowed and not
extended horizontally or vertically.
3. Hook and sheave assemblies must be
securely fastened to prevent swinging.
4. All loose accessories, tools, and remote
controls must be securely stored in their
respective compartments or fasteners.
5. The PTO must be disengaged.
6. The parking brake must not be released
until all of the above procedures are
completed.
7. Do not drive the carrier vehicle while a load
is present on the hook.
8. Do not drive the carrier vehicle with less
than proper tire inflation.
9. Do not drive the carrier vehicle in areas
where the vertical clearance is unknown.
10. Do not allow personnel to ride on the
equipment during transport.

Hook Precautions
1. Hooks are designed and manufactured to lift
specific loads. The specified rated load of a
hook applies to loads held uniformly in direct
tension and does not take into account
shock loads, hook tip loading, side loading,
bending, torsional, or related loads.
2. Do not attempt to lift a load that is larger
than the load rating of the hook.
3. Never use a hook’s yield point as an
indicator of its capacity.
4. Do not use a hook to lift personnel.
5. Know the rated load of the hook in use.
6. Never weld attachments to a finished hook
in field applications. This will alter and
destroy the design properties of the hook
material.
7. Keep fingers, hands, body, and loose
clothing from between the hook and the
load.
8. Avoid shock loading.
9. Inspect the hook regularly for excessive wear
and maintain it in safe operating condition.

The crane MUST be in the stored position before transporting.

pressures.
5. Keep the crane and service body
clean and free from grease build-up, oil
and dirt to prevent slippery conditions.
6. Perform all safety and maintenance
checks before each period of use.
7. Replace parts with Stellar Industries, Inc.
approved parts only.
8. Immediately repair or have repaired
any components found to be
inadequate.
Maintenance Procedures
1. Position the crane where it will be out of
the way of other operations or vehicles in

Failure to lubricate shaft splines will cause
damage to the PTO and Hydraulic pump.

Service
The following general suggestions should
be helpful in analyzing and servicing your
crane. Using the following systematic
approach should be helpful in finding and
fixing problems:
1. Determine the problem.
2. List and record possible causes.
3. Devise checks.
4. Conduct checks in a logical order to
determine the cause.
5. Consider the remaining service life of
components against the cost of parts
and labor necessary to replace them.
6. Make the necessary repair.
7. Recheck to ensure that nothing has
been overlooked.
8. Functionally test the new part in its
system.

Inspection Checklist
For a more detailed outline of scheduled
inspection points, refer to the Stellar
Inspection Checklist at the end of this
chapter. This list is an excellent guide for the
inspection tasks that will help maintain the
quality of your Stellar product. Feel free to
photocopy the checklist as needed.

Stellar Industries recommends the first
filter change to occur after the first 250
hours of service.* The second, and
every subsequent change, should
occur after every 1,000 hours of
service. By following these guidelines,
the hydraulic oil should last up to
6,500 hours.
*Note: These recommendations are based on normal
working parameters. If operating in less than favorable
conditions (excessive dust, moisture, etc.), be sure to check
the filter gauge often for filter change notice.

Holding Valve Inspection Procedure
The cylinders are equipped with holding
valves that prevent sudden movement of
the cylinder rods in the event of a hydraulic
hose or hydraulic component failure. The
valve is checked in the following manner:
1. Identify the cylinder in question.
2. Identify the holding valves and the
cylinder direction in question.
a. Cylinder Extend.
b. Cylinder Retract.
3. Place the machine so that the cylinder
will be located in the appropriate testing
position.
4. Pick the load (Do not exceed capacity,
rated or stability).
5. Disengage hydraulics.
6. Operate crane functions.
A. If the cylinder creeps (lowering the
load), replace the holding valve.
B. If the cylinder does not creep (load
stays suspended), the valve is
operational.
Gear-Bearing Bolt Maintenance
Anytime a gear-bearing bolt is removed, it
must be replaced with a new bolt of the
identical grade and size. Once a bolt has
been torqued to 75% of its proof load and
then removed, the torque coefficient may
no longer be the same as when the bolt was
new thus giving indeterminate damp loads
after torquing.

Warning!
Failure to replace gear-bearing
bolts may result in bolt failure due
to metal fatigue causing serious
injury or even death.

When using the torque data in the charts
above, the following rules should be
observed.
1. Bolt manufacturer’s particular
specifications should be consulted when
provided.
2. Flat washers of equal strength must be
used.
3. All torque measurements are given in
foot-pounds. To convert to inch-pounds,
multiply by 12.
4. Torque values specified are for bolts with
residual oils or no special lubricants
applied. If special lubricants of high stress
ability, such as Never-Seez compound
graphite and oil, molybdenum disulphite,
colloidal copper or white lead are
applied, multiply the torque values in the
charts by the factor .90. The use of Loctite
does not affect the torque values listed
above.
5. Torque values for socket-head capscrews
are the same as for Grade 8 capscrews.

Chapter 6 - Installation
Notice: Read this Page Before Installation of the Crane
General Installation
Installation Notice
This chapter is designed to serve as a general guide
for the installation of a Stellar 28000 Articulating
Crane on a Stellar Service Body. Each installation is
considered unique so certain portions of this chapter
may or may not apply to your direct application. If a
question should arise during the installation process,
please contact Stellar Customer Service at (800) 321
3741.
This crane is designed for use with a Stellar Service
Body installed on a vehicle that meets the minimum
chassis requirements of the crane. Check with Stellar
Industries before installing this crane on a body other
than a Stellar Service Body.

WARNING!
The use of this crane on a body not
capable of handling the loads imposed on
it may result in serious injury or death.
Notice:
PTO and Pump installation instructions are provided
by the corresponding manufacturers. For more
information on which PTO and Pump fit your
application, please contact your local Stellar
Distributor or Stellar Customer Service.

According to Federal Law (49 cfr part 571), each
final-stage manufacturer shall complete the vehicle
in such a manner that it conforms to the standards in
effect on the date of manufacture of the incomplete
vehicle, the date of final completion, or a date
between those two dates. This requirement shall,
however, be superseded by any conflicting provisions
of a standard that applies by its terms to vehicles
manufactured in two or more stages.
Therefore, the installer of Stellar cranes and bodies is
considered one of the manufacturers of the vehicle.
As such a manufacturer, the installer is responsible for
compliance with all applicable federal and state
regulations. They are required to certify that the
vehicle is in compliance with the Federal Motor
Vehicle Safety Standards and other regulations issued
under the National Traffic and Motor Vehicle Safety
Act.
Please reference the Code of Federal Regulations,
title 49 - Transportation, Volume 5 (400-999), for further
information, or visit
http://www.gpoaccess.gov/nara/index.html for the
full text of Code of Federal Regulations.

Installation Overview
For more detail, please contact
Stellar Customer Service
1. Relocate any obstructions on the frame that will be in the
way of mounting the crane.
2. Measure the inside of the frame rails and cut the frame
support to this length. Ensure that the frame supports have
a tight fit between the frame rails.
3. Set the crane on the chassis and allow a minimum of 2”
from the cab.
4. Install the crane tie downs. Start at one corner and tighten
both tie downs to 200 ft-lbs. Move to the diagonal set and
tighten to 200 ft-lbs. Tighten the remaining 2 corners.
Continue this pattern at 200 ft-lb increments until 650-700 ftlbs is achieved. Be sure the mounting block stays
perpendicular to the frame rail as they are tightened
down.
5. Connect the pressure and return lines per the hydraulic kit.
6. Connect the (+12V) power and ground wires.
7. Check the reservoir for oil and fill if necessary.

Hydraulics - Electrical

Chapter 8 - Hydraulics - Electrical
WARNING!
Please read the following section before performing any work on the hydraulic/electrical
system of your crane. This section contains vital safety information and maintenance
guidlines for your crane. If questions should arise, please contact
Stellar Customer Service at 800-321-3741
Never modify or alter any of the
equipment, whether mechanical,
electrical, or hydraulic, without Stellar
Industries’ approval.
Release system pressure before attempting
to make adjustments or repairs.
Do not attempt service or repair when PTO
is engaged.
Disassemble and assemble hydraulic
components on a clean surface.
Clean all metal parts in a nonflammable
cleaning fluid. Then lubricate all
components to aid in assembly.
Hydraulic fluid expands when heated. This
raises the pressure in an unventilated tank.
Release the tank pressure before removing
the cap completely. Failure to do so may
cause the oil to shoot out of the tank very
rapidly and cause severe burns.
Warning! If hydraulic fluid escapes, the
boom or crane can fall immediately.
Make sure the ground or blocking is
supporting the boom before performing
any maintenance or repair. Do not rely on
the hydraulic fluid to support the boom or
crane.

Contaminants in a hydraulic system affect
operation and will result in serious damage
to the system components. Dirty hydraulic
systems are a major cause of component
failures.
If evidence of foreign particles is found in
the hydraulic system, flush the system.
When installing metal hydraulic tubes,
tighten all bolts finger tight. Then , in order,
tighten the bolts at the rigid end, the
adjustable end, and the mounting
brackets. After tubes are mounted, install
the hoses. Connect both ends of the hose
with all bolts finger tight. Position the hose
so it does not rub the machine or another
hose and has a minimum of bending and
twisting. Tighten bolts in both couplings.
Due to manufacturing methods, there is a
natural curvature to a hydraulic hose. The
hose should be installed so any bend is
with this curvature.

Troubleshooting

Chapter 10 - Troubleshooting
This chapter will list a number of
potential problems that may occur
while operating the crane. Most
problems are easily solved using the
solutions portion of this chapter. If
problems persist, please contact
Customer Service at Stellar Industries
1-800-321-3741.
Problem: Crane will not operate.
Solutions:
• Make sure that the parking brake is engaged.
• Make sure that the PTO is engaged.
• Make sure that there is 12V power going to
the radio receiver. If there is no power going
to the receiver, trace back to the power
source and check for a blown fuse or loose
ground connection.
• Make sure that the transmitter batteries are
fully charged. (Rechargeable batteries are
good for 11 months or 200 charges)
• Make sure that the hydraulic pump is
operating at its rated flow or GPMs. Check
the flow by using the flow meter to determine
the GPMs. It is possible that the hydraulic
pump is getting weak. If this is suspected,
contact Stellar Customer Service.
Problem: Crane operates slowly.
Solutions:
• Make sure that the crane is receiving the
recommended GPMs to operate.
• Check the level of hydraulic fluid in the
reservoir. Add fluid as needed.
• Check to see if the valve bank proportional
valve is operating.
• Make sure the proportional valve is receiving
12V power when operating a function.

Problem: Crane will operate manually but
will not operate electrically.
Solutions:
• Make sure that there is 12V power going to
the radio receiver. If there is no power going
to the receiver, trace back to the power
source and check for a blown fuse or loose
ground connection.
• Make sure that the parking brake is engaged.
• Make sure that the parking brake switch is
working properly. Check the parking brake
switch by performing a continuity test. If the
switch is defective, simply replace it.
• Make sure the “Power” LED is on outside the
receiver door cover. This light is the upper
light on the receiver door. If the light does not
come on, check wiring back to the fuse. If
the fuse is OK, check system ground wires
and connections.
• Make sure the green LED on the receiver
door is lit green. This light will come on when
the red e-stop is pulled upward and the toggle
switch is activated on the transmitter. If the
radio system does not link up and no green
light is lit on the receiver - make sure that the
battery is fully charged, check the battery
contact points to make s ure they are not
tarnished or corroded. Clean contact points
and recharge or replace the battery.
• When battery voltage is acceptable, the
power LED light on the transmitter will be
solid. If the voltage becomes low, the LED
light will begin to blink and the battery will
need to be charged or replaced.

If problems persist, please contact
Stellar Customer Service at:
1-800-321-3741

28000 Owner’s Manual

Problem: Not all crane functions operate
using the radio remote transmitter or crane
operates intermittently.
Solutions:
• Make sure that the function switch is working
properly. If the switch is defective, simply
replace it.
• Make sure that there is power going from the
valve bank twin solenoid or to the function
that will not operate. If no power is going to
the twin solenoid, check wiring connections
on wire harness plug connector for broken
wires, loose connection or poor crimp. If
power is going to the solenoid valve, it may
not be opening to allow hydraulic oil to the
function that is not operating. Check the twin
solenoid for polarity, if solenoid does not
magnetize, replace the twin solenoid.

Problem: Cylinder drifts outward or
downward.
Solutions:
• Check to see if there is air in the hydraulic
system. Operate all cylinders connected to
the hydraulic system. Start with the extension
cylinder, then operate the main boom, winch,
rotation, and ending with the hydraulic
outriggers, if installed. When operating,
extend each cylinder halfway out, retract all
the way in, and then extend until the cylinder
rod is at the end of its stroke. Operate
cylinders slowly so air is pushed thru the
system to the reservoir. Repeat this cycle 2-3
times.
• Make sure the holding valves are operating
properly. Remove, clean, and then inspect
each holding valve. When removing a
holding valve, always relieve the pressure
inside the cylinder by loosening jam nut of the
holding valve and turning set screw
inward/clockwise. Count the number of turns
until the set screw is seated. When
reinstalling the holding valve, make sure the
valve is reset by turning the set screw the
number of turns it took to relieve the
pressure. Finish by tightening the jam nut.
• Check the cylinder rod for scratches. If a
scratch is located on the cylinder rod,
hydraulic fluid can pass thru and cause a loss
of pressure. Replace cylinder rod or cylinder.
• Check to see if the piston seals are damaged.
If they show signs of damage, install a new
cylinder seal kit.
Problem: Outer “Extend” and Extension In and
Out will not operate Manually or Remotely.
Solutions:
• Check to see if the functional cut out connector,
located on the valve section is lit. Note:
Functional cut out connectors will have an LED
light on when electrical power is present
• Check to see if there is 12 volt power going to
functional cut out connector.
• Check to make sure the Bosch relay is
functioning properly. It is located just behind
the panic bar E-stop switch. If functional cut out
connector is lighting properly, check to make
sure the connector is tight.
